Title: Method and apparatus for the manufacture of 2:2-dipyridyl
IPC: B01J19/00
Filed: 1961-01-17
Abstract: <PICT:0897473/III/1> <PICT:0897473/III/2> Apparatus for the production of 2,21-dipyridyl comprises in Figs. 1 and 2 a boiler 3 opening into an insulated casing 5 which in turn opens into a condenser 6 open to the atmosphere. In Fig. 1 a liquid-permeable sintered glass disc 8 extends across a tubular reaction vessel 7 which rest coaxially within 5 a side tube 9 opens into the space between 8 and the end of 7 to extend upwardly along part of the length of 7 Raney nickel catalyst 10 covered by pyridine 11 is placed in 7 to rest on 8. In operation a further quantity of pyridine 12 is boiled in 3, the vapour passes up through 5 to the condenser 6 in which it condenses and falls back through 7 some of the pyridine is forced through the catalyst 10 and the reaction products together with unreacted pyridine are forced upwardly through 9 and fall back into 3. In Fig. 2 a tube 13 closed at the lower end rests within 5 and is partially filled with catalyst 14 and then filled up with pyridine 15 a funnel 16 is inserted axially into 14 the pyridine 12 is boiled in 3 and the vapour passes up to 6 where it condenses and falls back into 16 some of the pyridine is forced through the catalyst where it reacts and the 2,21-dipyridyl and unreacted pyridine are carried into 3.ALSO:2,21-Dypyridyl is produced by maintaining Raney nickel in contact with pyridine at elevated temperatures, the products including 2,21-dipyridyl being removed from contact with the catalyst continuously or intermittently by displacement with pyridine. The unreacted pyridine may be separated from the product, e.g. by distillation, and recycled to the reactor. Preferably the pyridine in contact with the catalyst is maintained at temperatures above 80 DEG C. The process may be carried out, for example, by percolating pyridine near its boiling point through a porous bed of dry Raney nickel catalyst so that the 2,21-dipyridyl is continuously removed by displacement by pyridine or the liquid pyridine near its boiling point is passed upwardly through a bed of catalyst so that the 2,21-dipyridyl and the unreacted pyridine overflow from the top of the receptacle containing the catalyst. Details of the apparatus for carrying out the process are given.

Title: Swimming Pool with Movable Interfloor
IPC: E04H4/06
Filed: 1968-06-18
Abstract: A swimming pool has an impervious interfloor, with edges flexibly sealed to the walls, which can be raised and lowered by means of a pumping system which draws water from above and below the interfloor through discharge lines and supplies an equal volume of water through supply lines to both levels, the discharge and supply lines contain adjustable valves whereby net transfer of water from below the interfloor to above it and vice versa can be effected to adjust the position of the interfloor. In a preferred embodiment the water level is kept at a constant height (6), Fig. 2 (not shown) by means of a recessed circumferential drain (7). A flat plate-like interfloor 8 is arranged to be moved parrallel to the pool bottom from a position at minimum water level above the interfloor to a position at maximum water level above the interfloor and vice versa, as shown. The interfloor is sealed around its edges by means (27) and is maintained horizontal by a guide such as lazy tongs 9. When the interfloor is moved to its lower position, per time unit more water is fed via a supply device 24 to the water space above the interfloor than is removed therefrom via a discharge device 21 by controlling the valves 28-31 which further ensure that more water is removed via a discharge device 13 from the water space below the interfloor than is fed thereto by a supply device 14, so that the interfloor is moved downwards by the water pressure. The opposite process raises the interfloor.

Patent ES-360151-A1 (ES)
Title: A method of producing and hot working continuous hollow castings
IPC: B22D11/14
Filed: 1968-11-12
Abstract: A hollow casting, e.g. of steel, is produced by the method described in Specification 1,088,909, i.e. a continuous casting is conveyed from a mould in a curved path, first downwardly, then upwardly to a level above that to which the molten core can rise, and then the hollow shell is compressed by at least one pair of rolls or at least one forging or pressing device (or more, in stages) so that the hollow space is eliminated and inner faces of the shell are welded together and subjected to hot working. For making billets of high-speed tool steel or ledeburitic Cr-steel for sheet or strip production, the shell thickness (controlled by adjustment of casting speed or direct water cooling) is not more than 50 mm. and there is a hydrogen atmosphere in the hollow space. The temperature of the casting is controlled by insulation or cooling to obtain the desirable hotworking temperature. Lengths may be cut from the strand, taking care to close the strand at the cutting point to exclude air, and reheated in a furnace to attain the hot-working temperature. Reference has been directed by the Comptroller to Specification 1,088,909.
